WINDOW-SCREEN.

Patented Feb. 20, 1906.

App filed September 6, 1905. Serial No. 277,152.

To all whom, it may concern.-

Beit known that I, DANIEL WESLEY KEITH, a citizen of the United States,residing at Keithville, in the parish of Caddo and State of Louisiana,have invented a new and useful Window-Screen, of which the following isa specification.

This invention relates to window-screens, such as are used for thepurpose of excluding insects; and it has particular reference to thatclass of screens which are adapted to be wound upon a roller connectedwith a window-sash, so that when the window is op en the screen will beunwound from the roller, and vice versa.

The objects of the present invention are to simplify and improve theconstruction and operation and with these and other ends in view, whichwill readily appear as the nature of the invention is better understood,the same consists in the improved construction and novel arrangement andcombination of parts, which will be hereinafter fully described, andparticularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein eX-hibited, but that the right is reserved to any changes, alterations, andmodifications to which recourse may be had within the scope of theinvention and without departing from the spirit or sacrificing theefficiency of the same.

In said drawings, Figure 1 is a front elevation of the lower portion ofa window-casing, the bottom of which is equipped with the improvedscreen, said bottom sash being shown in a raised position. Fig. 2 is avertical sectional view taken on the plane indicated by the line 2 2 inFig. 1. Fig. 3 is a front elevation-showing the bottom sash partlyraised without unrolling the screen. Fig. 4 is a sectional view,enlarged, taken on the plane indicated by the line 4 4 in Fig. 1 andshowing in plan the screen-casing, a portion of which has been brokenaway. Fig. 5 is a sectional view, enlarged, taken on the plane indicatedby the line 5 5 in Fig. 1.

Corresponding parts in the several figures are indicated throughout bysimilar characters of reference.

In carrying this invention into practical operation, a casing, 1 ofsuitable shape and of devices of the class referred to; I

dimensions, is provided, said casing being preferably constructed ofsheet metal and provided at one edge with a flange 2 for the receptionof means, such as nails-or screws, whereby it may be secured in positionupon a sash-rail. In the accompanying drawings it has been shown appliedto the bottom rail of a lower sash, and the fastening-flange is at theupper edge of the casing. If the casing or fixture is applied to anupper sash, its position will be reversed, as will be readilyunderstood. The casing is provided at the edge opposite to thefastening-flange with a slot or .opening 3,overwhich a curved lid, as 4,projects. The ends of the casing afford bearings for the ends of a shaft5, carrying a roller 6 and provided adjacent to the ends of said rollerwith spur wheels or pinions 7. screen 8, made of foraminous flexiblematerial, such as wire-gauze, is attached to and adapted to be woundupon the roller 6, and the free edge of said screen is attached to acleat 9, Which may not be drawn through the slot. 3. To the ends of thecleat 9 are secured a pair of rack-bars 1O 10, that extend through slots11 in the ends of the casing 1, and beneath said rack-bars, are secureda pair of strips 11, of sheet metal, which extend back of the casing andwhich constitute fenders or guards to prevent insects from enteringbetween the edges of the screen and the windowcasing. These fenders maybe secured in position when the device is applied to the window in orderto compensate for the slight variation in width of various casingssupposed to be of standard size, such variation being frequently causedby unequal shrinkage. Said fenders will thus serve to fill any possiblespace between the rack-bars and the sides of the window-casing.Additional fenderstrips 12 overlapping one another at their inner endsare secured to the sash-rail adjacent to the securing-flange of thescreen-casing, said fender-strips being provided with upturned hooks 13at their outer ends, which extend under the fender-strips 11 anddraftbars 10 to prevent said strips and bars from spreading. Thesash-rail 14, opposite to that with which the screen-casing isconnected, is provided with loops or guards 15 for the reception of thefree ends of the rack-bars when the screen is rolled.

Upon the sill of the window-casing is secured a catch 16, adapted toengage and to hold the cleat 9 at the free edge of the screen when saidcleat rests upon the sill.

ICC

When the bottom-sash, to which the device has been applied, is raisedwhile the cleat 9 is in engagement with the catch 16, the roller will berotated by the 'pinions 7 engaging the rack-bars 10, thus unwinding thescreen to the height to which the sash is raised. When the sash islowered, the screen is wound upon the roller. When it is not desired touse the screen, the disengaged from the cleat 9, and then when the sashis raised it will carry with it the entire casing, containing thescreen-roller, together with the cleat 9, the rack-bars 10, fenders 11and related parts, as will be clearly seen in Fig. 3 of the drawings.

Having thus described the invention, what is claimed is 1. Ascreen-casing having an attachingflange at one edge and a slot at theopposite edge, a roller supported for rotation in said casing and havingspur-wheels at the ends thereof, a flexible screen upon the roller, acleat at the free edge of the screen, and rackbars connected with saidcleat and extending through the screen-casing in engagement with thespur-wheels.

2. A screen-casing having a slot, a roller supported for rotation insaid casing and provided with spur-wheels, a screen connected with theroller and extending through the slot, a cleat at the free edge of thescreen, rack-bars connected with the cleat and projecting through thecasing in engagement with the spur-wheels, and fenders connected withthe casing beneath the rack-bars.

3. The combination with a window-sash, of a screen-casing connectedtherewith having a slot, a roller supported for rotation in said casingand having spur-wheels, a screen connected with the roller and extendingcatch 16 is simply through the slot in the casing, a cleat connectedwith the free edge of the screen, rackbars connected with the cleat andprojecting through the casing in engagement with the spur-wheels, andmeans for detachably connecting the cleat with the window-casing.

4. The combination with a window-sash, of a screen-casing connectedtherewith and having a slot, a roller supported for rotation in saidcasing and having spur-wheels, a flexible screen connected with theroller and extending through the slot in the casing, a cleat connectedwith the free edge of the screen,

rack-bars connected with the cleat and pro' jecting through the casingin engagement with the spur-wheels, fender-strips connected with thecleat and extending beneath the rack-bars and between the screen-casingand the sash-rail upon which the latter is mounted, and auxiliaryoverlappingfender members having upturned ends engaging thefender-strips and the rackbars.

5. The combination with a window-sash, a casing connected therewith, ascreen-carrying roller in said casing, a cleat at the free edge of thescreen, and spur-wheels upon the screen-carrying roller; of rack-barsconnected with the cleat and projecting through the casing in engagementwith the spur-wheels, and loops or guards for the reception of the freeends of the rack-bars upon the rail of the sash opposite to that withwhich the screen-casing is connected.

In testimony that I claim the foregoing as my own I have hereto aifixedmy signature in the presence of two witnesses.
